if yer asking for plug suggestions NGK
Did the plugs also
big improvement overall but still a lil hestation
I am thinking the mass air flow sensor may be out of range.
Junkyard? or new one?
Aftermarket or OEM?
I know its gonna be expensive no matter what.
did you check the o2 sensor? id check that first before spending alot of money on a mass air flow sensor
heres the positive fix...
get all the intake manifold and carb off of a carbed truck and switch it over!!
you can probably do that for the cost of a mass air-flow sensor...lol
Just a thought.
